While his split from the Toon was bitter, Isak was determined to defend the club's Saudi owners in the wake of pressing questions from the local Swedish mainstream media.
Asked about his controversial departure, the striker said to Sportbladet: "I can say this: Things are always more complicated than they seem.
"I have talked about this, but I have not gone into depth. And it is not something that I want to do, based on the fact that I have put it behind me.
"I am focusing forward, there is no benefit in going into it or opening it up – neither for me nor for anyone else. It must remain in the past."
Isak was also asked about joining Newcastle after they had been bought by the Public Investment Fund: "We understand how things can be twisted and turned. You can find negative things when it comes to everyone, and different things in our society.
"I think you have to take it for what it is. It's an English club in the best league in the world, a step in your career."
'Sportbladet' then pushed Isak about 'condemning' players for signing with Newcastle. He replied: “No. I think that’s a very long shot. It’s a Premier League club, playing in England, in the best league in the world.
“If you have that option, it feels very far-fetched that you should say no to it because of their owners. From my perspective, a footballer’s perspective, as I said, you go to a Premier League club."
